Description
WordPress Plugin WooCommerce is prone to a vulnerability that lets attackers download arbitrary files because the application fails to sufficiently verify user-supplied input. This may allow an attacker to gain access to sensitive information, which may aid in launching further attacks. WordPress Plugin WooCommerce version 3.4.5 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 3.4.6 or latest
